I think for the new setting we're discussing, then that `C-f' should not
alter the selection (just like `open' doesn't today with the selections
it chooses).  That is, `C-x h' would say "put all of this in the
selection", just like `C-a' in Firefox does.

I think that sounds good for the t setting.
